It is an interesting concept. I recall that Donald Trump "sold" his dad a bunch of chips (in the millons) from one of his AC casinos when he was having a cash crunch back in the late 80's. The story was that it was better for his dad than making a loan because in the case of a bankruptcy chip holders get paid first and note holders get in line at the bankruptcy court. I seem to recall that the regulators were upset about it. It would seem to me that places doing a lot of collectible chips - like the Hardrock - would eventually have a very large amount of float on the books and the formula for determining the "bank" requirement would get rather large in comparison to what is really need to back the games. But then I suppose the amount collectors account for is just noise when compared to the total required to support the games. And when you think about people lining up to get a shot at buying chips - chips you know they intend to keep - it does sound like a missed opportunity for the state to get a little revenue...
